IMPROVEMENT IN PUMPS.

Speciication forming part of-Letters Patent N9. 218,569, dated August12, 1879; application filed Y January 14, 1879.

To all whom it may concern:

Be it known that I, WILLIAM J. PIRKLE, of Cumming, in the county ofForsyth, and in the State of Georgia, have invented certain new anduseful Improvements in Pumps; and do hereby declare that thefollowing'is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, making a pai-t of this specification.

The nature of my invention consists in the construction and arrangementof a pump, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, in which-Figure 1 is a central vertical section of my pump. Fig. 2 is a plan viewof the same.

A represents a chest or reservoir, on top of which the bellows B issecured, with a passage, a., leading from the chest into the bellows. Ois the top plate or disk ofthe bellows, provided with a slide or othervalve, D, in the center, which may be held closed by means of a latch,D. F is the receiving-tube, provided with a valve, b, at the inner endin the chest A. I is the discharge-tube, provided with a valve, d., atits outer end.

The pump may be made of any suitable material, so as to be air-tight,and is intended for the purpose of raising and purifying water, by thecontact of air, from wells or cisterns or reservoirs, `or for extractingany kind of'liquid from any vessel or reservoir, and for eX- tinguishingiire.

The pump is to be operated by hand or by machinery, by means of a leverattached to the top disk, G, of the bellows, to force the water from thedischarging-tube.

By attaching an extra tube, of hose or other material, with a valveacting in the same manner as the one on the discharging-tube, the airmay be forced to the bottom of the well or reservoir continually as thewater is extracted. The valve D on top of the bellows is for the escapeof air.

By turning the latch Dl to one side, a piece of hose, of rubber or othersuitable material, may be attached to inclose the valve and reach to thebottom of the well, through which the air is then forced as the bellowsclose, thus supplying the water with fresh air. which puries it from thepoisonous gases that iufest water excluded from the air. The valve D isalso used to secure the filling of the reservoir when the valve on theescape-tube is closed. The latch D' is used to give power to force waterfrom the escape-tube through hose for the extinguishing of tire, tc.

For drawing water ordinarily, the valve D on top, and the one ou the endof the escapetube. may both be allowed to work, or either of them, ascircumstances require.

Having thus fully described Iny invention, what I claim as new, anddesire to secure by Letters Patent, is-

The withindescribed pump, consisting of the chest A, bellows B, withvalve D in its top plate, the receiving-tube F, with valve b, anddischarge-tube I, with valve d, all constructed substantially as and forthe purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this6th day of December, 1878.

WILLIAM J. PIRKLE.
